325_driver 422 Report post Posted April 12, 2008 hey guys just doing the last touch up before my 325 motor goes in brake lights are always on ? the brake lines are empty and i havent bled them, can that cause the lights to be on ? or would it be a relay problem ? what about a wire earthing out? cheers Quote Share this post Link to post Share on other sites
ducatiss 1 Report post Posted April 13, 2008 I would fill your braking system and bleed it first, then if there is still a problem, tackle it from there. Is your brake pedal fully up when your lights on on? Quote Share this post Link to post Share on other sites

QuickSilver 0 Report post Posted April 13, 2008 (edited) I'm going to assume its an e30 your talking about, and can almost be certain that the brake light sensor is the problem, (the one above the brake pedal) just adjust it, common problem. Bleed the brakes because its good to do it anyway. Edited April 13, 2008 by QuickSilver Quote Share this post Link to post Share on other sites

Yep, if you mean rear lights then will be this switch, could also be faulty, if the later version switch then could also be adjustment as said Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted April 13, 2008 um, when it stops raining ill start fiddling round with things, cause its pouring but how bout this, i was putting some relays in, matching up my 325 relays and putting them in the 320 (e30's) is it possible that putting a relay in, when its not supposed to be there, it could make the brake lights always go. im assuming theres probably not supposed to be a brake light relay. correct ? shouldnt really need a relay?
